What is this worm?

[Remmy]

We are new to saltwater and just set up our first tank last weekend. We have been noticing more and more critters come out of the live rock every day. Today we noticed this worm. We also have some Little star fish that seem to be getting eaten. They had all their legs yesterday and today they are only half there. Could this worm be eating them?

Welcome to R2R!!! Hard to tell from the pic. Look like a Fireworm https://www.google.com/search?q=Eur...i9jNAhUm8IMKHQbwAXgQ_AUICCgB&biw=1920&bih=955

Thank you! Could this work be eating our star fish?

Bristleworm, good clean up crew, just not so pretty. Asterina stars can become a nuisance later. They are splitting, how they reproduce.
And don't touch the bristleworms, those fuzzy hairs on the side sting.

Thank you very much! That is very helpful! Maybe the star fish aren’t as cool as I thought.

I'm thinking fireworm also. Here's a helpful guide to hitchhikers: https://www.lionfishlair.com/hitchhikers-guide/

Here are some better pictures. It is between 8-10 inches long. Is one that big okay?

That is a big worm. You should make a worm trap.

Those reddish tufts say fireworm!! Get him out! And be careful.
And welcome to r2r !!

Welcome to R2R! I'm also going to say that is a fireworm. The other picture is a asterina starfish. Some are good some are bad and it's almost impossible to tell them apart. I would pull them out IMO.

Thanks everyone for the help!

Unless it has the word "tube" attached to the front of it, I had the word "worm". Urgh. Welcome to R2R. Us newbies in the hobby need to stay together.
